Show amount of energy consumed from grid while energy was produced / not produced

[Gitsarry]

To have data for better decision base in the question if it would economically make sense to buy more solar panels and/or energy storage to increase energy-self-production and reduce costs, I think it would be helpful to see in the energy dashboard:

• The amount of energy consumed from grid while solar panel produced at least 5% of production peak value, meaning the sun was shining somehow. So this energy consumed from grid could potentially be self-produced with more solar panels. (e.g. when having 600 W peak, show energy consumed from grid while panel produced at least 5% * 600 W = 30 W)
• The amount of energy consumed from grid while solar panel produced nothing (meaning no sunshine). This amount of energy could not be self-produced with more panels alone. Only in combination with energy storage.
